Abstract

A rule based apparatus and method for modifying word annotations in an annotated text base, the apparatus comprising: an index creator component for creating an index of word annotations; an annotations modifying component for modifying word annotations; and a retriggering component, responsive to said annotations modifying component, for retriggering a rules engine to modify all occurrences of a matching word annotation in said annotated text base and updating the index of word annotations with the modified occurrences of a matching word annotation in said annotated text base.

Claims

1. A method for modifying word annotations in an annotated text base, comprising:

creating, by a processor, an index of word annotations by;

creating an annotation array that indexes annotations assigned to terms in the annotated text base, the annotation array comprising annotations and references for each annotation from the annotated text base; and

creating an index that indexes the annotated terms in the annotated text base, the index comprising a list of all words in the annotated text base and for each word, the assigned annotation and a list of references;

modifying a select annotation to an updated annotation;

modifying all annotation occurrences in the index that match the select annotation, to the updated annotation; and

updating the annotation array with a reference to the modified occurrences of the select annotation in the annotated text base.

2. The method of claim 1 further comprising identifying a word associated with a document to be stored in the annotated text base.

3. The method of claim 2, wherein on identifying a word, creating a reference to the identified word in the created index of word annotations.

4. The method of claim 1 further comprising identifying a number associated with a document to be stored in the annotated text base.

5. The method of claim 4, wherein on identifying a number, creating a reference to the identified number in the created index of word annotations.

6. The method of claim 1 further comprising identifying a punctuation mark associated with a document to be stored in the annotated text base.

7. The method of claim 6, wherein on identifying a punctuation mark creating a reference to the identified punctuation mark in the created index of word annotations.

8. The method of claim 1 further comprising checking in the index to determine if there is already stored a reference to a word in the annotated text based.

9. The method of claim 8, wherein responsive to a positive determination by the indexing step, the annotation modifying component modifies the annotation associated with the word in the annotated text base to the annotation associated with the determined reference.

10. The method of claim 1 further comprising:

creating an XML representation of the index.

11. The method of claim 1 further comprising:

performing a check function on the index in response to executing a dictionary rule, to determine whether there are any terms that match a word specified in dictionary rule; and

iterating through the index for all indexed terms that match the specified word in the dictionary rule to update the associated annotation.

12. The method of claim 1 further comprising:

creating a new index entry in response to processing a rule that results in no matches in the index.

13. The method of claim 12 further comprising:

adding a multi-word term to the index;

selecting the first word of the multi-word term;

using the index to determine whether any references exist for the first word in any registered documents of the annotated text base;

examining each located reference to determine whether the located term is part of a longer phrase that matches the multi-word term; and

updating the annotations array.

14. The method of claim 1, wherein creating an index that indexes the annotated terms further comprises adding count data that counts the number of references for each indexed term.

15. The method of claim 1, wherein modifying a select annotation to an updated annotation is in response to implementing rules.

16. The method of claim 1, wherein modifying all annotation occurrences is in response to modifying a select annotation to an updated annotation.
